Starting with the basics - I purchased this unit in early Jan. 2017, and this is my first inversion table devise. Packaging of the product is excellent .... well laid out in the box and protected with plastic wrap and foam blocks to keep contents secure. Assembly is very easy with the assistance of very clear instructions , all necessary stainless fasteners, and even a simple tool kit provided. Quality materials are used throughout the entire unit and the padding is very comfortable. I'm 6'-2" and over 250LBS , and this unit easily adjusts to my size and is rock solid. If you are new to this type of devise (as I am) , I would suggest easing into a "just slightly" inverted position .... then pause to assess your personal comfort level , verses getting yourself fully inverted right away, in order to minimize the blood rush to your head and possible dizziness. The amount of inversion can be pre-set before you even step into it, by means of an adjustment strap, allowing you to set your comfort level ahead of time ..... this is a nice feature. I really liked the comfortable and firm feel of the ankle supports and the longer handle of the ratchet mechanism. For me, favorable back adjustment and pain relief is nearly instantaneous with this product , with just limited inversion angles required. Improved spine alignment did in fact make movement easier , and afterwards I did feel a bit taller .... but the absence of pain was a very pleasant sensation. Each user will be different, but the duration of time required on this table to achieve some level of relief is under a minute. When not in use, it folds up into a slim profile using minimal space , still standing on its own , or leaned against a wall like a step ladder. In summary , I would highly recommend this quality product, which is capable of providing safe,comfortable and controlled relief to a wide variety of people of different age groups , weights , and sizes.
